CAR SIDE. BEARING.

SPECIFICATION forming part of Letters Patent No. 545,255, dated August2'?, 1895.

Application tiled April l 1, l 8 95 To @ZZ when?, 15 may concern:

Beit known that we, FRANCIS G. SUSEMIHL and AUGUSTUS Tonner, citizens ofthe United States, residing at Detroit, inthe county 0f NVayne and Stateof Michigan, have invented certain new and useful Improvements in CarSide Bearings, of which the following is a specification, referencebeing had therein to the accompanying drawings.

The invention consists in the construction ot a side bearing for cars;audit consists in the construction, arrangement, and combination of thevarious parts, all as more fully hereinafter described.

This is intended to bean improvement upon the prior patent of F. G.Susemihl, No. 311,618, of February 3, 1885.

In the drawings, Figures l and 2 are t'ront` elevations of the device,showing the parts in different positions. Figs. 3 and 4 are similarelevations of a slightly-modified form of our invention. Fig. 5 is a topplan view of our improved bearing. Fig. 6 is a vertical longitudinalsection, and Fig. 7 is a vertical central cross-section thereof.

The object of our invention is to provide a roller-bearing between thecar-body and truck which shall reduce the friction between those partsas a car moves around a curve in the track and in which the rollers willalways be maintained in proper relation to the upper and lower plates,or car and bolster plates.

A is the bolster-plate, andB is the carplate, these plates being securedby suitable means to the bolster and car, respectively, one above theother. The plate B is centrally apertured, and depending around thelower edge of the aperture is the llange C, iittingin a gain or recessI) in the end of the bolster. This recess has an end opening E, so thatany dust or cinders falling through the aperture in the plate may dropout upon the ground.

F is a segmental dat track or runway for the rollers F', which have endtrunnions G, jonrnaled in the sides of the carriage II. This carriage iscurved longitudinally to conform to the shape of the track F. Its upperedges run within the anges u. on the lower edges of the plate B. Theseiianges have inwardly-cut grooves b, in which the guidedianges c on thetop ot the carriage engage, and thus prevent the dropping of thecarriage ordisarrangement Serial. No. 545,372. (No model.)

of the parts when the car-body is lifted from the truck, as in makingrepairs. On the under face of the plate B, between the flanges a, is aflat segmental circular track or bearing I, which rests on the top ofthe rollers, forming an opposite runway for rollers, as mentioned forlower plate. It becomes necessary with such a construction of bearingcomprising a carriage between the bolster and body to have some means tomaintain the rollers always in the same relation to the tracks on whichthey run, regardless of whether the truck bears on the rollersconstantly or not. This we have shown accomplished by means of a singlecoupling-bar .I in Figs. 1, 2, 5, 6, and 7 and by two of such bars K inFigs. 3 and 4:.

In the single-bar construction we have shown the upper plate providedwith an aperture to receive the bar, and on the sides ot the aper tureare the saddle-bearings L, in which the ends of the trunnion L on thetop of the bar rest. The carriage is provided with the vertical guides Mon the inner face of its sides, in which the circular lugs or bosses Nengage and are adapted to slide vertically in the operation of thedevice. The lower end of the bar engages in the central aperture in thebolster-plate and is preferably formed with an enlarged head d, havingcurved sides. In use, as the car goes around a curve the upper platemoves on the rollers, and the carriage moves in the same direction withone-half the speed, the coupling-bar maintaining the plates and carriagein proper relation to each other at all times. The different positionsof the parts are illustrated in Figs, l and 2, and also in themodification shown in Figs. 3 and 4t.

In the construction embodying the double coupling-bars the bars dependat the ends of the car-plate, and theirlower ends bear against the sidesof the bolster. On its inner edge the car-plate is provided with theemergencyflange O, arranged above the face P on the bolster-plate, sothat in case the carriage is broken these faces will form a bearingbetween the car and truck.

From the description heretofore given it is evident that when thebolsterplate is in its normal middle position the rollers will he heldin their middle position, as shown in Fig. 6. Justin proportion as thetruck turns at an angle to the car in going around a curve the ICCrollers will travel to one end under the top plate, resting on thebolster-plate. It is also .evident that this coupling-bar alwayscontrols the relation of the rollers to the plate and maintains them inproper position, regardless of whether the car-plate or bolster-platebears against the rollers or not.

Although the rollers are normally moved by the contacting plates, yetthe coupling-bar is needed to move the carriage or rollers in case theplates should separate or the rollers should tend to become displacedfrom any other cause, such as gradual displacement.

What we claim as our invention isl. In a side bearing for cars, thecombination of the car plate, the bolster plate, a roller carriagebetween said plates, flanges on the carriage engaging grooves in the carplate, for the purpose described, and means for con` trolling themovement of the carriage on the car plate, substantially as described.

2. In a side bearing for cars, the combination of the car plate, thebolster plate, a roller carriage between, flanges on the carriageengaging grooves in the car plate for the purpose described, and acoupling bar suspended from the car plate acting to control the movementof the carriage, substantially as described.

3. In a side bearing for cars, the combination of the car plate, thebolster plate, the roller carriage between, and a coupling bar suspendedfrom'the car plate, passing through the carriage, and having its lowerend engaging the bolster plate for the purpose described.

4:. In a side bearing for cars, the combination of the apertu red earplate, the apertured bolster plate, the intermediate roller carriage, acoupler having trunnions at the top, saddle bearings in the car plate inwhich the trunnions are supported, lugs on the side of the bar, verticalguides in the carriage with which said lugs engage, and the head asdescribed engaging bearings on the bolster plate.

5. In a side bearing for cars, the combination of the car plate, thebolster plate, the roller carriage between said plates, and theemergency flanges O, P on said plates, as and for the purposes setforth.

In testimony. whereof we affix our signatures in presence of twowitnesses.
